T o'ctll whom it may concern:

Be it known that I, ANDREW C. Tnonr- SON, citizen of the United States, residing at Falfurrias, in the county of Starr and State of Texas, have invented new and useful Improvements in Means for Closing the Ends of Conduits, of which the following is a specification.

My invention has to do with means for closing the ends of irrigation pipes and other conduits; and it seeks the provision of a simple, inexpensive and easily applied valve for the purpose stated, and one adapted to be used to advantage on an iron pipe or a tile pipe, and capable of being readily adjusted to take up wear and for other purposes.

The invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

, Figure 1 is a perspective view illustrating the valve constituting the preferred practical embodiment of my invention as the same appears when open. Fig. 2 is an enlarged view, partly in side elevation and partly in section, showing the valve as closed. Fig. 3 is an enlarged detail section showing the preferred connection between the cam lever and the connecting bars of my improvements.

Similar letters designate corresponding parts in all the views of the drawings, referring to which:

Ais a section of irrigation or other pipe, and B is a clamp which I preferably, though not necessarily, employ to effect connection of the working parts of the valve with the pipe section. I prefer to employ the said clamp B for the purpose stated because it is readily applicable to pipes of different materials and also because it is adapted to be expeditiously and easily adjusted to render the leverage, presently described, tight or loose, as desired by the operator.

C C are the connecting bars which are pivotally connected to and extend forwardly from the clamp B, and D is a valve body, interposed between the forward portions of the bars C. The said valve body is provided with notches a to hold it against turning on the bars, and is also provided with projections 1) disposed in slots 0 in the bars, this latter provision being resorted to in order to prevent the valve body dropping too far when the same is raised. The said valve body is further provided on its upper portion with a rearwardly directed flange E. This latter is designed when the valve is closed. or opened to overhang the end of the pipe A and in that way prevent the water spurting up on the operator of the valve, and to keep the valve from dropping too low. I I would further have it understood that when deemed desirable the valve body D may be provided at its rear side with a suitable packing (Z and at its forward side with a wear plate 6.

In addition to the elements thus far described, my improvements comprise a cam lever F which is disposed in front of the valve body D and is formed integral with a tube f journaled on a bolt G which extends between and is secured in the forward ends of the connecting bars C.

In the practical use of my improvements it will be seen that when the valve body D is raised as shown in Fig. 1, the end of the pipe A is left entirely unobstructed and it will also be seen that when the valve body is lowered to a position opposite the end of the pipe, and the lever F is depressed, as shown in Fig. 2, the valve body will be crowded against the said end to preclude the escape of water therefrom. Incidental to either the closing or opening of the valve, the flange E will serve the purpose ascribed to itt. (5., will prevent the head of water spur-ting up on the operator of the valve. I would further have it understood that the valve body I) may be secured by props or other suitable means, which I have deemed it unnecessary to illustrate, at any stage of opening so as to utilize any desired. part of the full capacity of the conduit A.

It will be gathered from the foregoing that my improvements in addition to being simple and inexpensive are easy of application to pipes of different kinds and are adapted to be easily kept in repair; also, that the valve as a whole is possessed of high efiiciency since when the valve body is locked against the end of the pipe in the manner shown in Fig. 2 there is no liability of water being permitted to escape from the pipe.

As before stated the construction herein illustrated and described constitutes the best practical embodiment of my invention of which I am cognizant, but it is obvious that in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim and desire to secure by Letters -Patent, is: v

1. In a valve, the combination with a conduit; of bars pivotally connected with the conduit, a valve body movable on the bars in the direction of the length thereof, means on the valve body, means on the bars for cooperating with said means on the valve body to limit movement of the body on the bars in the direction of the length thereof, and a cam lever mounted between the bars and arranged in front of the Valve body.

2. In a valve, the combination with a conduit; of bars pivotally connected with the conduit and having slots, a valve body hav ing notches receiving the bars and also having projections movable in the slots thereof, and a cam lever mounted between the bars and arranged in front of the valve-body.

3. In a valve, the combination of a conduit, bars pivotally connected with the conduit and having slots/a valve-body having a rearwardly directed flange and also having notches receiving the bars and projections movable in the slots thereof, a bolt extending between the bars and arranged in front of the valve-body, and a cam lever journaled on said bolt and adapted to engage the valvebody and crowd and hold the same against the end of the conduit.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
